looks like wiring issue check your TX on your printer and RX on your ESP |
The wire seems to be ok y checked the continuity between the esp TX, RX and the FTDI pin on the board (the board doesn't have TX and RX pin). I even try to invert the TX RX cable but in this case nothing works... I can't really understand how it can work fine from the ESP3D to the printer but not in the other way. If the wire were bad nothing would work right ? Sorry i'm really a beginer so what info do you need ? |

it is wire / connection issue |
Ok I effectively had a bad wiring Everything works fine thank you ! |

Hello,
I'm using ESP3D on a ESP01 connected to a gt2560 board with marlin on it.
The commands works fine, I can do home and control the temp but it seems that the informations goes only in one way : from the ESP3D to the printer. The other way doesn't work, the printer doesn't send any info... I can't see or upload (even with 8.3 file format) files in the SD card, the graph temp stay empty and nothing appear on the command pannel.
I try M115 or M20 and nothing happens
